Akai 42in rear projection TV convergence problem

The TV shows double and triple images. Unable to fix it with the built in convergence menu. Had the cable company come out to see if it was a cable problem, they said that it is the convergence module of the TV.
Is this worth fixing.? Any idea of the cost?
I've sent numerous e-mails to Akai, they just don't answer.
Thank you for any help.

Picture showing double. Red color is warped.


This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some images of convergence problems.

I have a Panasonic HDTV Projection PT-47WX42 with double imaging.


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Blue and Yellow doubles


Well, fortunately the television that you purchased has an auto-convergence feature. What is happenning is that your color lamps are misaligned, did it get moved at all recently? Anyway, in your menu you should see a "Convergence" menu, and inside that menu, a section called "Perfect Focus". Run Perfect Focus in this sequence: Green --> Red --> Blue After that your picture should look great, if not try tinkering with the manual adjustments on the "Convergence" menu.
